The chromatographic column is made of seamless cold-drawn 316L stainless steel tubes, with an inner surface roughness of less than 0.1 µm and an outer surface roughness of less than 0.6 µm. It has upper and lower long mirrors for visual operation and is equipped with stainless steel sintered filters and chromatographic liquid distribution plates to control the uniform distribution of the chromatographic liquid and maintain a uniform chromatographic velocity. The bottom of the column has multiple channels to ensure that multi-phase chromatographic liquid is discharged separately without interfering with each other. The flow rate of the chromatographic liquid can be controlled and measured online. The feed into the column is automatically controlled, and the flow rate can be adjusted and measured online to ensure consistent feed and discharge flow rates, thereby better controlling the purity of anthocyanin extraction. Online backwashing, online resin activation, and the resin column are simple and convenient to use.
